Parsing XML with T-SQL in two separate tables - sql-server

Question

Using SQL Server 2012 and trying to parse an XML to 2 separate tables in my database. Normally 1 table would be enough, but not in this instance. My XML is structured as follows (I can't change it's structure, I already receive it like that)
<?xml version="1.0" encoding="utf-8" standalone="yes" ?>
<podjetje id="" storitev="" uporabnik="" ts="" opis_storitve="">
<izdelki>
<izdelek st="1">
<izdelekID>ID</izdelekID>
<ean>EAN CODE</ean>
<izdelekIme>PRODUCT NAME</izdelekIme>
<url>WEBSITE</url>
<kratkiopis>SHORT DESCRIPTION</kratkiopis>
<opis>DESCRIPTION</opis>
<dodatneLastnosti>ATTRIBUTES</dodatneLastnosti>
<slikaVelika>BIG PICTURE URL</slikaVelika>
<dodatneSlike>
<dodatnaSlika1>EXTRA IMAGE URL</dodatnaSlika1>
<dodatnaSlika2>EXTRA IMAGE URL2</dodatnaSlika2>
<dodatnaSlika3>EXTRA IMAGE URL3</dodatnaSlika3>
</dodatneSlike>
</izdelek>
</izdelki>
</podjetje>
To insert this XML into a table i use SQL bulk insert
SET #SQLString = 'INSERT INTO tmpImport(XmlCol)
SELECT *
FROM OPENROWSET(BULK ''' + #ImportFileName + ''', SINGLE_BLOB, ERRORFILE = ''' + #BulkLoadFilePath + ''') AS x '
EXECUTE (#SQLString)
I can handle most of the data without any problems. I ran into some problems when i get to the node "dodatneSlike". The idea is, that each article has some pictures. The main picture is in the node "slikaVelika" and I can insert it into my table. There are extra pictures in the child nodes of node "dodatneSlike". This is causing me problems, because I have to insert these extra pictures into a separate table (inserting the picture from node "slikaVelika" would also help, but I think i can get around it if it's not possible). The table is nothing special, just the Article ID from node "izdelekID" and the pictures from "dodatneSlike".
The problem is, I never know how many nodes ("dodatnaSlika1", "dodatnaSlika2",...) there will be. There might be 1, 10, 0....
So my question is how do I get the values from "dodatnaSlika" nodes?

Try to use the native XQuery support in SQL Server! Much easier than the clunky old OPENROWSET stuff....
You can try something like this:
DECLARE #input XML = '<?xml version="1.0" encoding="utf-8" standalone="yes" ?>
<podjetje id="" storitev="" uporabnik="" ts="" opis_storitve="">
<izdelki>
<izdelek st="1">
<izdelekID>ID</izdelekID>
<ean>EAN CODE</ean>
<izdelekIme>PRODUCT NAME</izdelekIme>
<url>WEBSITE</url>
<kratkiopis>SHORT DESCRIPTION</kratkiopis>
<opis>DESCRIPTION</opis>
<dodatneLastnosti>ATTRIBUTES</dodatneLastnosti>
<slikaVelika>BIG PICTURE URL</slikaVelika>
<dodatneSlike>
<dodatnaSlika1>EXTRA IMAGE URL</dodatnaSlika1>
<dodatnaSlika2>EXTRA IMAGE URL2</dodatnaSlika2>
<dodatnaSlika3>EXTRA IMAGE URL3</dodatnaSlika3>
</dodatneSlike>
</izdelek>
</izdelki>
</podjetje>'
SELECT
izdelek_st = #input.value('(/podjetje/izdelki/izdelek/#st)[1]', 'int'),
izdelekID = #input.value('(/podjetje/izdelki/izdelek/izdelekID)[1]', 'varchar(50)'),
ean = #input.value('(/podjetje/izdelki/izdelek/ean)[1]', 'varchar(50)'),
XC.value('local-name(.)', 'varchar(50)'),
XC.value('(.)[1]', 'varchar(50)')
FROM
#input.nodes('/podjetje/izdelki/izdelek/dodatneSlike/*') AS XT(XC)
This will give you all the subnodes under <dodatneSlike> - no matter how many there are - and it gives you both the node name, as well as the node value.
Update: assuming you have multiple <izdelek> nodes, then you could use this query instead:
SELECT
izdelek_st = #input.value('(/podjetje/izdelki/izdelek/#st)[1]', 'int'),
izdelekID = xc1.value('(izdelekID)[1]', 'varchar(50)'),
ean = xc1.value('(ean)[1]', 'varchar(50)'),
XC2.value('local-name(.)', 'varchar(50)'),
XC2.value('(.)[1]', 'varchar(50)')
FROM
#input.nodes('/podjetje/izdelki/izdelek') AS XT1(XC1)
CROSS APPLY
xc1.nodes('dodatneSlike/*') AS XT2(XC2)
